The avant-garde pop genius Arthur Russell worked in obscurity for most of his too-short career. He died of complications from AIDS in 1992, at the age of 40. About a decade after his death, Russell’s music went through a huge reappraisal, and it remains tremendously influential now. Russell had left behind a vast trove of unreleased music, and that music has been coming out ever since, one collection at a time. Amazingly, there’s still music left in those vaults. In a couple of months, we’ll get a whole new Arthur Russell album.
